UNITED STATES VEHICLE OPERATED GATE AND m'rcn John Bock, Salem, Mo. Application March 25, 19st, Serial No. 133,063

4 Claims. (ciao-2s) A This invention relates to improvements in swinging gates.

The object of the invention is to provide a. gate adapted to be used across a roadway that will 7, be automatically opened by a vehicle striking the gate, and will return automatically to a closed and latched position after the vehicle has passed.

A further object of the invention resides in the in provision of guard members to protect the gate structure from injury when being opened by a vehicle driving against it.

Another object of the invention is to provide means to be engaged by a vehicle to release the i gate latch to allow the gate to swing open when pressed against.

Other objects and advantages of the invention will become apparent from the description and drawings, wherein Figure 1 is a view in elevation of the gate in a closed position,

Figure 2 is a longitudinal sectional view on the line 2-4 of Figure 1, v

Figure 3 is an enlarged fragmentary crosssectional view on the line 3-3 of Figure 1,

Figure 4 is an enlarged fragmentary sectional view on the line 3-4 of Figure 3,

Figure 5 is a fragmentary elevational view partly in section on an enlarged scale showing in 0 detail one of the hinge members,

Figure 6 is a View similar to Figure 2 showing the invention as applied to a metal gate,

Figure 7 is an enlarged fragmentary crosssectional view on the line 1-4 of Figure 6, D

Figure 8 is an enlarged fragmentary sectional view on the line 8-8 of Figure 6,

Figure 9 is an enlarged fragmentary plan view partly in section showing the modified means of mounting the hinge member, and

Figure 10 is an enlarged plan view showing the modified means of mounting the keeper, the post being shown in section.

Referring more particularly to the drawings wherein like reference characters designate like or corresponding parts in the different views, a gate II is adapted to be mounted upon a gate post l2 by means of brackets 13 and i3 secured to the post l2 and which have studs It and it projecting upwardly from the brackets l3 and it to receive the looped ends l5 of hinge straps lb.

The gate l l comprises the three sets of vertical members ill, the four horizontal members It fastened between members l7, and the diagonal braces I9.

55 Horizontal guard members are mounted on each side of gate l l by means of brackets 24] which are secured to the opposite sides of two oi the sets of vertical members ill. The free ends 22 of members 2% have resilient plates 23 which curve inwardly and bear against gate ii, permitting the 5 looped about ends 27! and secured by a fastening 2e. Between the loop portions 28 is a cut out portion 36 to permit brackets to engage over ends 21. The loops 2% are secured fast to ends 27 while the ends 21 are adapted to revolve in brackets 25 so that when buiier plates 2d are pressed inwardly the cranks 2% will swing rearwardly or toward post it.

A sliding bolt or latch 30 is mounted on gate ll by means of U-shaped brackets 32 secured to the members ll. The bolt is adapted to slide horizontally in openings 33 of the U-shaped brackets 32.

A gate post 3d is adapted to support a keeper 3% having a recess portion 36 to receive the end 3i of bolt M. The keeper 3?: is provided with cam surfaces 38 to depress bolt 3i when the gate is being closed so that end it can engage recess 36.

A sleeve member 3% is adjustably secured to end 6 M of bolt 3i by adjustment screw til as seen in Figures 3 and 4. The ends d2 of sleeve 3% extend downwardly and are secured together by a nut and bolt $3. The portions s2 are provided with openings M, as seen in Figure 4, to receive the cranks 26 which are adapted to be engaged by openings M. The free ends at of cranks as are bent downwardly to prevent disengagement from the opening M.

The bolt 3! has a coil spring tlli mounted thereon which is secured between one of the brackets 32 and a pin M which is mounted in an opening 68 in bolt 3i. The spring lli normally urges the end 3'! into engagement with recess 36.

The bracket it is provided with cam surfaces M which extend upwardly on each side from a, point opposite to where bracket i3 is secured to post it. Strap is is adapted to ride up onto these cam surfaces all when the gate is swung to an open position on either side.

The stud M is provided with a nut Ed threaded to its upper end, as seen in Figure 5,'to hold a coil spring 5! which is mounted on stud it. The lower end of spring 5! bears against a washer 52 which in turn bears against the upper face of loop ll. ing ll.

In operation, assuming the gate to be closed, I

as in Figure :1, an automobile approaching the gate will strike one of the buiier plates 24 causing end 22 of guard member to give against. the

' action of plate 23, and at the same time buiier 24 will swing inwardly causing crank 28 to swing rearwardly carrying sleeve is and bolt 3| rearward with it, and compressing spring 46. 1111s will release end 31 from the keeper 3! so that the gate II can be pushed open by the automobile. When the'vehicle has passed the coil spring}! bearing down on loops l6 will cause strap I! to slide down the cam surface 49 swinging the gate to a closed position, In the meantime spring 46 a will expand so that end 31 will engage cam sur- 4 until eiid 31 reaches the recess 36 when the bolt 3| will be pressed out by spring 46 so that end I! will be held in engagement with recess 36. It is to be understood that the action will be the same when gate I I swings open in the opposite direction. If it is desired to have gate remain in an open position, it may be accomplished by pushing the gate to the full open position, so that strap I! will pass beyond the cam surface 49 and on to the upper horizontal side of bracket i3 so that the spring 5| will not cause the gate to return to its closed position.

Figures 6, 7, 8, 9, and 10 show the invention as applied to a metal gate. The post 54 has a U-shaped bolt 55 secured to it which supports a plate 56 which carries brackets l3 and I3. The strap hinge i5 is bent and fastened to the vertical post 51 by member 58 which is bolted to strap ii to clamp it on post 51 as best seen in Figure'9. The gate H comprises the three vertical members 51 and the two horizontal members 60. The guard members 20 are secured to the members ,51 by the brackets 2| The bolt Si is mounted on one side of member 51 by brackets 6| which are provided with a loop portion 62 to receive bolt" 3| as best seen in Figure 'l. The post '63 has a bracket 64 secured thereto which carries keeper 35. The rest of the parts can be used interchangeably and will not be described again. The operation of the gate is of course the same.-

It is to be understoodthat only the preferred embodiment of the invention has been vshown the right being reserved to make such changes and modifications as will not depart from the spirit of the invention.
